The SCPNT was administered to 73 female and 32 male volunteer subjects ranging in age from 21 to 60 years with a median educational level of 13 yeares. Subjects were divided into four age groups and a 4 (Age group) by 2 (Sex) analysis of variance was performed using postrotary nystagmus duration as a dependent measure. The results revealed a significant age main effect. Scheffe post hoc tests suggested that the two older age groups (41 - 50 and 51 - 60 year) had significantly longer nystagmic duration than the younger groups (21 - 30 and 31 - 40 years). The need to control for age in studies using the SCPNT with adults is discussed.
